This is more consistent with what the Rust bits of the style system do, and removes a pointer from ComputedStyle which is always nice. This also aligns the Rust bits with the C++ bits re. not treating xul pseudos as anonymous boxes. See the comment in nsTreeStyleCache.cpp regarding those. Can't wait for XUL trees to die. Depends on D19001 Differential Revision: https://phabricator.services.mozilla.com/D19002 --HG-- extra : moz-landing-system : lando
